Different heat can be generated at the same time by controlling the current (the thermal power is W ═ i)2R and R are electric heating wires, i is the current magnitude) to control the deformation degree of the memory alloy. A simple constant current source power supply can be constructed by adopting a three-terminal voltage-stabilizing integrated circuit LM 317. Compared with the change of the direction of a driving air pressure valve of equipment such as a motor, the memory alloy sheet is low in driving speed and can take 5 s or 6s for complete deformation, but the requirements of the application are met by the memory alloy sheet through an extremely simple mechanical structure, extremely small space occupation and low cost.
